Answer
(-$\frac{3}{8}$) $\times$ ($\frac{13}{14}$) $\times$ (-$\frac{12}{9}$) = $\frac{13}{28}$
Work Step by Step
(-$\frac{3}{8}$) $\times$ ($\frac{13}{14}$) $\times$ (-$\frac{12}{9}$) =
Multiply the numerators by each other, and multiply the denominators by each other
$\frac{(-3) \times 13 \times (-12)}{8\times14\times9}$ =
Factor the numerator and the denominator
$\frac{(-3) \times 13 \times (-2) \times 2 \times 3 }{2\times2\times2\times2\times7\times3\times3}$ =
Cancel the common factors between the numerator and the denominator to obtain :
$\frac{(-13)\times (-1)}{2\times2\times7}$ =
$\frac{13}{2\times2\times7}$ =
$\frac{13}{28}$
